Free Wildcard SSL Certs are coming to Let’s Encrypt

Let’s Encrypt will release wildcard SSL certificate support in January 2018. This will ease the burden of adopting and deploying SSL in cases where multiple subdomains need SSL support. From the official announcement on July 6, 2017:

A wildcard certificate can secure any number of subdomains of a base domain (e.g. *.example.com). This allows administrators to use a single certificate and key pair for a domain and all of its subdomains, which can make HTTPS deployment significantly easier.

Wildcard certificates will be offered free of charge via our upcoming ACME v2 API endpoint. We will initially only support base domain validation via DNS for wildcard certificates, but may explore additional validation options over time. We encourage people to ask any questions they might have about wildcard certificate support on our community forums.
